Notes:
Yeasts were chemostatically cultivated on C2-substrates. Experimental yield figure were 0.77 g/g and 0.57 g/g on ethanol, 0.37 g/g and 0.29 g/g on acetate and ammonium and nitrate, respectively, as the nitrogen sources. Growth on hexadecane/ammonium yielded 0.94 g/g. Simultaneous utilization of formate lead to an increase of growth yield on acetate and hexadecane but not on ethanol. The experimental data were compared to theoretical figures. These results show that growth yield on ethanol/ammonium is carbon-limited, on ethanol/nitrate is NADPH-limited and on acetate with both nitrogen sources is energy-limited. With hexadecane/ammonium growth yield is energy-limited too. According to these results ethanol seems to be the only substrate from which an excess in energy can be obtained.
